SHOE-LAST.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Orig nal application filed May 10, 1913, Serial No. 766,811. Divided and this application filed January 2, 1915. Serial no. 165.

To all whom it may concern:

Be it known that I, EDWIN J. Pnmnnn, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain Improvements in Shoe-Lasts, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasts, and articularly to lasts having a removable eel part to provide, for example, for removal of the heel part while the forepart remains in the shoe in order to facilitate heeling on the jack, or the substitution of a filler heel part after those operations which require a very strong and rugged heel part have been completed by the aid of such heel part.

The general object of the present invention is to provide a last of the type having separable fore and heel parts which will have all the above-named and other advantages characteristic of lasts of this type as heretofore constructed and which will be at the same time stronger, simpler in construction and consequently cheaper to manufacture, and more readily manipulated and operated than lasts of th type heretofore known.

A feature of the invention is a hinge connection comprising headed studs on drfl'erent levels on one of the two separable parts (there being one or several studs on any level, as desired) and a hinge plate on the other last part having notc es in different planes substantially parallel to the plate, to engage the studs. This arrangement of the notches permits them to be easily seen by the operator while removing or attaching the heel part while the forepart is in the shoe, these operations being difficult under such circumstances since the cramped quarters interfere greatly with ease in manipulation. In the last shown in the drawings, the studs are arranged with the lower farther to the rear than the upper. This structure admirably serves the purpose described.

The invention also comp rises a novel bonding means for holding the last parts together when in extended position. This means comprises a member on one last part and two members on the other last part constructed and arranged to engage and grasp the former member between them. In the last shown, one of the latter two members is a hinge plate which moves relatively toward the other as the hinge expands to.extended position.

Another feature of the invention consists in a novel locking means for a hinge last, comprising a bail attached to one part of the last and a hook shaped arm mounted on the other last part and engaging the bail so that the arm is always held against accidental displacement from its normal operative path.

These and other features of the invention will be understood from the following description of a preferred embodiment thereof, selected for purposes of illustration.

In the accompanying drawings,

Figures 1, 2 and 3 are, respectively, a plan view and longitudinal sectional views of a shoe last embodying my invention;

Fig. 4 is a side elevation of a shoe last embodying my invention;

Fig. 5 is a rear view of the toe part of the last;

Fig. 6 is a transverse vertical sectional view of Fig. 1;

igs. 7, 8 and 9 are, respectively, front, side and back views of the forward plate of my hinge connection;

Figs. 10, 11 and 12 are similar views of the rear plate of my hinge plate connection;

Figs. 13 and 14 are front and side elevations of a locking piece; and

Figs 15 and 16 are similar views of the spring.

The last which is the subject of my invention is of the type having a, toe and heel part readily detachable from each other so that a standard heel part can be used with several or many styles of toe parts, thus reducin the cost of lasts in a factory, since not al the styles of toe parts are in use at the same time. For this style of last it is obviousl desirable to have the heel part indestructlble or as nearly indestructible as possible, because the greatest strains come upon the heel part. In the accompanying drawings, the toe art 1 is shown as connected with the heel part 2 by the following connection: Headed studs 3 are secured in the rear face of the toe part as by rivets 4, there preferabl being one upper and two lower studs. hese studs are adapted to be engaged by a forward plate 5 of a hinge connection which plate is shown in Figs. 7 to 9. The said plate 5 has two lower notches 6 which, like keyhole slots,are adapt ed to fit over and behind the heads of the lower studs 3, and it is rovided with an upper notch 7 that is pre erably formed in the turned-over upper end 8 of the plate, such and at its sides having ears 8, to which are riveted ears 9 formed on the body of the plate. The notch 7 thus stand in a plane forward of the notches 6 so that the said notch can be open at its bottom, instead of being a true keyhole slot, as it would have to be if it were formed in the body of the plate 5. This permits engagement of the plate 5 with the three studs by a simple downward movement. The plate 5, at its lower end, has two ears 1O bent rearward therefrom, which are connected by rivets or a pintle 11 with cars 12 on the rear hinge plate 13. At its upper end, the rear hinge plate has ears 14 in which i pivoted the U- shaped locking iece 15 shown in Figs. 13 and 14, as by a rivet or pintle 16. The locking piece is engaged under a bail 16 secured in a vertical plane in the forward plate 5 as by havin its ends passed through said plate and hea ed over. The U shape in which the member 15 is shown is regarded as preferable but, if desired, a hook arranged to engage the bail 16' may be used. I regard the bail broadly as a hook. The lower end of the plate 13 is bent forward as at 13, so that when the hinge is 0 en and the last extended, as in Fig. 2, said e ge 13 will project under the heads of the lower studs 3, and thus lock the hinge connection from riding up and becoming detached from said studs. A spring 17, as shown in Figs. 15 and 16, has its front and rear ends 18 and 19, respectively, connected b a loop 20 which is only partially closed? so that said loop can be sprung over the intle 16 and removably hold the spring in p ace, thus providing for its ready renewal in case of breakage. The forward end 18 of the spring is preferably forked to straddle the bail in the collapsed condition of the hinge. The rear end of the spring rests a ainst the plate 13, and the forward end under the legs of the locking piece 15 so that the spring normally tends to throw the locking piece up.

When the locking piece is thrown down, as. shown in Fig. 3, and the hinge collapsed,

.the forward Plate can be engaged with or disengaged from the studs on the fore part by a simple vertical movement, because the portion 13 of the rear hinge plate is removed :Erona beneath the studs. When the last is by opening the hinge, the

spring throws the locking piece to the upper end of the bail, and in tlns position the locking piece prevents either collapse or a further extension of the last. The portion 1 of the rear hinge plate also engages the stud heads from below and thus locks the hinge on the studs.

I do not describe or claim herein the novel construction of last heel disclosed, since I have claimed it in my application Serial No. 766,811, filed May 10,1913, of which this case is a division.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United Stats is 1.
